Abstract:

A convenient and efficient method for the preparation of α-substituted β-amino acids has been developed by reacting compound 2 with various boric acid/borate 3 through Suzuki coupling reaction, which gave multiple structure types of substituted Ni(II) complexes 4 in high yields. Hydrogenation and hydrolysis of complexes 4 led to the corresponding α-substituted β-amino acids.

Key words: Ni(II) complex, Suzuki coupling reaction, α-Substituted β-amino acids
